How to recognize it

Key identification clues

  • Dark stalks fork into spreading branches.
  • Small leaflets form broad, nearly horizontal fans.
  • Spore-bearing areas occur along leaflet edges beneath folded margins.

Where and when to look

Look in moist, humus-rich woodland soil, especially on shaded slopes and in ravines. The deciduous fronds die back for winter.

Compare similar plants

Follow the dark branching stalks and the arrangement of the leaflets. The fanlike outline is more useful than the delicate texture alone.

A closer look

Branching fans

The main axis divides into two branches that spread into a broad fan.

Dark wiry stalks

Reddish-black to dark stalks contrast with the green leaflets and help reveal the branching pattern.

Folded leaflet margins

The folded edges protect spore-bearing areas. Ferns reproduce by spores and do not produce flowers.
